Schools to Produce Trove of Intellectual Property

'The meticulous scoring of videotaped lessons for this project is unfolding on a scale never undertaken in educational research, said Catherine A. McClellan, a director for the Educational Testing Service who is overseeing the process.

'By next June, researchers will have about 24,000 videotaped lessons. Because some must be scored using more than one protocol, the research will eventually involve reviewing some 64,000 hours of classroom video. Early next year, Dr. McClellan expects to recruit hundreds of educators and train them to score lessons.

'The goal is to help researchers look for possible correlations between certain teaching practices and high student achievement, measured by value-added scores. Thomas J. Kane, a Harvard economist who is leading the research, is scheduled to announce some preliminary results in Washington next Friday. More definitive conclusions are expected in about a year.

'The effort has also become a large-scale field trial of using classroom video, to help teachers improve and to evaluate them remotely.'
